ABSTRACT:
A serial communications protocol is provided that has mandatory features such as an idle code feature and optional features such as an optional automatic lane polarity reversal feature and an optional automatic lane order reversal feature, an optional clock tolerance compensation feature, an optional flow control feature, and an optional retry-on-error feature. A user that desires to create a protocol-compliant integrated circuit design can either choose to include or to not include the optional features. Integrated circuits in which the optional features are implemented are able to perform the associated functions. Integrated circuits in which the optional features have not been implemented are not able to perform these functions, but can be fabricated using fewer circuit resources.
